Answer:
√6 + √2
= --------------
4
Step-by-step explanation:
15° = 45° - 30°
So
cos(15) = cos(45 - 30)
=cos(45) × cos(30) + sin(45) × sin(30)
= 1/√2 × (√3)/2 + 1/√2 × 1/2
(√3) + 1
= --------------
2√2
(√3) + 1 √2
= -------------- x ---------
2√2 √2
√6 + √2
= --------------

Midpoint formula
Let S denote the midpoint of R and T
Answer:
c
Step-by-step explanation:
18x³y⁴ = 2 * 3 * 3 * x³ * y⁴
24x²y⁵ = 2 * 2 * 2 * 3 * x² * y⁵
GCF = 2 * 3 * x² * y⁴ = 6x²y⁴
18x³y⁴ + 24x²y⁵ = 6x²y⁴(3x + 4y)
